Technical Accuracy and Userfriendliness of Two Point-of-care C Reactive Protein Devices in Comparison With Laboratory CRP Testing.

User-friendliness

evaluation of the userfriendliness by General Practitioners at 5 practices, on a five point Likert-scale scoring these criteria: device start-up, test duration, sample size, test characteristics, calibration, measuring range, handling of test tubes, filling of the capillary, placing the test cartridge, test recording and additional material usage. The median results are compared between both devices qualitatively.

Time frame: 3 months

Inter-device variability

The inter-device-variability (by 1 physician) was tested on 10 patients in one General Practice surgery each on two different Point-of-Care devices of the same brand.

Time frame: 3 months

Inter-observer variability

The inter-observer variability (by two physicians) was tested on 10 patients in one GP surgery on two different Point-of-care devices of the same brand.

Time frame: 3 months
